Police sergeant charged with assault over watch house 'attack' after CCC investigation

A Perth police sergeant has been charged with assault over an alleged attack on a detainee at the Perth Watch House in 2012.

The charge follows an investigation by the Corruption and Crime Commission, which claims the police officer grabbed a 31-year-old man by the throat, pushed his finger into his eye and forced him to the ground.

He then allegedly continued to hold him by the throat, causing breathing difficulties.

The matter was reported to the watch house custody supervisor by other staff and referred to the CCC after an internal police investigation.

The officer is expected to appear at Perth Magistrate's Court next month.
